[vtk-developers] VTK 7.1 issue with vtkPoints while rendering

[afnanahmad]

Here is the code I'm using, not sure which step is wrong.

vtkSmartPointer<vtkPoints> points = vtkSmartPointer<vtkPoints>::New();
vtkSmartPointer<vtkCellArray> cell = vtkCellArray::New();

for (size_t i = 0; i < point_cloud->points.size(); i++)
{

	double point[3] = { point_cloud->points[i].x,
		point_cloud->points[i].y,
		point_cloud->points[i].z };

	vtkIdType id = points->InsertNextPoint(point);

	cell->InsertNextCell(1);
	cell->InsertCellPoint(id);
}

vtkSmartPointer<vtkPolyData> polyData = vtkSmartPointer<vtkPolyData>::New();
polyData->SetPoints(points);
polyData->SetVerts(cell);

vtkSmartPointer<vtkVertexGlyphFilter> glyphFilter =
vtkSmartPointer<vtkVertexGlyphFilter>::New();
glyphFilter->SetInputData(polyData);
glyphFilter->Update();

vtkSmartPointer<vtkPolyDataMapper> mapper =
vtkSmartPointer<vtkPolyDataMapper>::New();
mapper->SetInputConnection(glyphFilter->GetOutputPort());

vtkSmartPointer<vtkActor> actor = vtkSmartPointer<vtkActor>::New();
actor->SetMapper(mapper);


for some of the files this code is working fine.
